Automotive relays offer small size, light weight

Maple Grove, Minn.  CIT Relay & Switch offers the A2 and A3 series relays for automotive applications. The devices feature a typical electrical life of 100,000 cycles with a mechanical life of 10 million cycles.

The A2 and A3 series automotive relays offer contact arrangements of SPST N.O., SPST N.C., SPDT and SPST N.O. on two terminals. Both styles offer PCB pin and quick-connect mounting. Copper alloy terminal strength is 8N for the quick-connect style and 4N for the PCB pin version. Contact resistance is <30 milliohms initially and insulation resistance is 100 megohms at 500 Vdc for both series types. Solderability is 260°C for 5 seconds. The operating temperature range is -40°C to 85°C.

The A2 series offers contact ratings up to 40 A at 14 Vdc, and up to 80 A at 14 Vdc for the A3 series. The maximum switching power for the A2 series is 630 watts with a maximum switching voltage of 75 Vdc and a maximum switching current of 40 A. The A3 series offers a maximum switching power of 1120 watts, a maximum switching voltage of 75 Vdc and a maximum switching current of 80 A.
